Commitment from everyone at 4NRJ to your project from the beginning to the end.
TECHNOLOGICAL DEVELOPMENTS
We aim to accompany our customers in the definition of their needs and objectives to reach. Our perfect
knowledge of the railway market and its key actors allows us to make proposals in bringing adapted
technical solutions facing problematics encountered.
According to your needs, we propose a custom specification from the beginning to the end of your global
project.
1/ CAO-DAO PROTOTYPING
Mission statement
The mission statement is done following a continuous collaboration between you and 4NRJ experts. This
is a real long-lasting cooperation during the different project phases. Needs analysis done, the project
design will be changing many times according to your new expressed needs. Exchange and consultation are
our key-words to make this requirements specification close to your exact needs.
2/ CAO-DAO Software
According to your needs, our experts design innovative tools adapted to your project using advanced
technologies. Those pioneering technologies allow us to present you shortly a graphic model that will be
moving towards according to your new development axis.
4NRJ’s team uses IT and digital tools (CAO-DAO) to design 3D models for having a complete vision of
your project.
This digital model, once validated, will be later launched to Production for having a prototype.
3/ PROTOTYPING
The prototype is an essential part of the Production process: it allows us to obtain shortly a physical
validation of this first part but also reduces drastically the product's development duration. The
prototype allows us to suggest you shortly a relevant physical solution in a fairly short time at lower
cost because a model created by fast prototyping can be achieved in a few hours.
INDUSTRIALIZATION
The prototype once validated, we accompany you to the Production process.
DESIGN
The prototype once validated, we accompany you to the Production process.
The product industrialization is ensured by reliable partners chosen by their expertise fields,
continuing the quality process commitment.
We accompany every single step of the Production, facing if necessary dimensional, functional and
regulatory constraints.
Our Production specific partners have been selected by their skills and capacity to solve all
constraints inherent to the project achievement.
SET-UP & AFTER SALES SERVICE
Ensuring often short delay, 4NRJ invests in terms of related HR recruitments and stock to respect
delivery dates.
Highly motivated and passionate about our job and especially appreciating collaborative tasks, 4NRJ Team
